Chemotaxis is the phenomenon whereby somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by swimming towards the highest concentration of food molecules, or to flee from poisons ...
Chemotaxis (from chemo- + taxis) is the movement of an organism or entity in response to a chemical stimulus. [1] Somatic cells, bacteria, and other single-cell or multicellular organisms direct their movements according to certain chemicals in their environment.
Chemotaxis is the directed migration of a cell toward a chemoattractant along a concentration gradient. The ability of neutrophils to undergo chemotaxis implies the possession of a sensory mechanism that must be linked to the locomotor apparatus of the cell.

Jan 1, 2022 · Definition. The term “chemotaxis” has been derived from two words – “chemo” meaning chemical and “taxis” meaning movement. Thus, it can be defined as the directed movement of a cell or an organism in response to chemical stimulus (Willard and Devreotes 2006 ).
Chemotaxis is the phenomenon in which the direction of a cell's locomotion is determined by an extracellular gradient of chemicals. The first recorded observations of chemotaxis were made in 1888 by Leber, who found that leukocytes converge from all directions along straight paths to sites of rabbit corneal irritation [1,2].
Aug 8, 2008 · Chemotaxis is a fundamental process in which cells migrate directionally when they are exposed to external chemical gradients. It is exhibited by a wide variety of cell types and involves distinct strategies that depend on the environmental conditions.
Chemotaxis is the directed movement of cells (or an organism) towards or away from a chemical source. A classical example of chemotaxis is the movement of immune cells, such as neutrophils or macrophages, towards chemoattractants released at sites of infection or injury (e.g. fMLP and CSF-1) [ 1 ].
Chemotaxis is the movement of organisms in response to a nutrient source or chemical gradient. Cells with chemotatic capabilities can sense xenobiotic chemicals adsorbed to soil particles and swim toward them, thereby overcoming the mass-transfer limitations in the bioremediation process (Fig. 28.6 ).
Chemotaxis is defined as directed movement of cells up or down a chemical gradient. Here we focus on chemotaxis in eukaryotic cells where the gradient sensing results in directed cell motion in the form of crawling. Eukaryotic chemotaxis is thought to be a key component in a multitude of biological processes.
